Sure.
One thing would be tactile walking surface indicators. When you get to the corners and there are little bumps on the ground, those are for us, to stop us from walking into traffic. They're very helpful. There are a lot of those in Japan.
One of the things that are interesting and that I've seen in many big cities—Japan was the first place I saw it—is that there are a couple of grooves in the middle of every sidewalk. You can put the tip of your white cane into that to follow that groove, or you can walk with your dog and keep your foot on it. It walks you straight down the sidewalk. That is an amazing feature for people, especially people who use canes. Unfortunately—because, again, of attitude, education and awareness—it's a wonderful feature until you come across the bike that's parked across it or the business that has decided to put its garbage across that line. Those are some of the things that do become barriers a bit.
One of the most interesting ones that I really enjoyed in Japan was when you go into their very well-known train system and put your hand on the railing to go up or down the stairs. When you get to the top or the bottom, underneath the railing is written, in Braille, what level you're at, what floor or which platform you're at. Sighted people don't notice it, but a blind person actually feels it with their fingers underneath as they're holding the railing. I love that feature. I thought it was amazing. If I could read Japanese Braille, it would be even better, but I thought it was a fantastic way of hiding a piece of accessibility and giving us a bit of an edge.
